Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foundation parting structure in which a parting edge is attached between an outer wall and a foundation.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 3, an outer wall 3 having a cavity 5 in a wall body is fixed to a wall fixing metal fitting 4 fixed on a foundation 1, and a parting edge 10 ″ is formed along a lower surface 3a of the outer wall 3. It is known that the structure is provided so that rainwater can be prevented from entering from the lower part of the outer wall 3 by the cut-off edge 10 ″. In the figure, 7 is an interior material and 21 is a sealing material.

[0003]

[Problems to be solved by the device]

 However, the conventional parting edge 10 ″ is used to prevent water from entering from the lower part of the outer wall 3, and the parting edge 10 ″ itself does not have a ventilation function, so that the parting wall 10 of the outer wall 3 is not provided. There is a problem in that dew condensation is likely to occur and the outer wall 3 is adversely affected such as warping and mold.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a basic parting structure in which a parting edge is provided with a ventilation function so that air inside an outer wall is always dried. To provide.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention attaches the outer wall 3 to the wall fixing fitting 4 fixed on the foundation 1, and forms a parting edge 10 between the outer wall 3 and the foundation 1 along the lower surface 3a of the outer wall 3. A ventilation port 16 is provided on the mounting and parting edge 10, and a ventilation hole 8 communicating with the ventilation port 16 is provided on the frame body 6 of the outer wall 3 having the cavity 5 inside.

[0006]

[Action]

 According to the present invention, a ventilation hole 16 is provided in the parting edge 10 which is attached along the lower surface 3a of the outer wall 3 between the outer wall 3 and the foundation 1, and the frame body 6 of the outer wall 3 having the cavity 5 inside. Since the ventilation hole 8 communicating with the ventilation hole 16 is provided, the outside air is taken into the cavity 5 of the outer wall 3 from the ventilation hole 16 of the cutting edge 10 through the ventilation hole 8 and the inside of the cavity 5 of the outer wall 3 is seen. The air can always be dried. Therefore, it is possible to prevent dew condensation in the wall body of the outer wall 3, which causes warping of the outer wall 3 and generation of mold.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the foundation parting structure of this embodiment is such that an mortar 2 is provided on a foundation 1, and an L-shaped wall fixing metal fitting 4 also serving as a base of an outer wall 3 (exterior material) is provided on the mortar 2. Is fixed. A cavity 5 is provided inside the outer wall 3 attached to the wall fixing bracket 4, and the cavity 5 is surrounded by a frame body 6 (furnace) of the outer wall 3 and an interior material 7 attached to the inside of the outer wall 3. In addition, the lower surface 6a of the frame body 6 is provided with a ventilation hole 8 for opening the cavity 5. The outer wall 3 is attached to the wall fixing member 4 by fixing the frame 6 to the wall fixing member 4 by welding or the like.

A parting edge 10 is arranged between the outer wall 3 and the foundation 1. The parting edge 10 includes a ventilation portion 11 arranged below the ventilation hole 8 of the frame body 6, and a waterproof portion 12 arranged along the lower surface 3a of the outer wall 3 in front of the frame body 6. The aeration part 11 is a horizontal part 13 placed on the mortar 2 so that the front end projects forward of the foundation 1, and the rear part which is erected at the rear end of the horizontal part 13 and fixed to the wall fixing fitting 4. It has a rising portion 14 and a front rising portion 15 standing on the front end of the horizontal portion 13. A drain hole 18 is formed on the front end side of the horizontal portion 13, and a water is formed on the front rising portion 15. The vent 16 is formed at a position higher than the hole 18. As a result, the hollow portion 17 of the ventilation portion 11 communicates with the outside through the ventilation hole 16 of the front rising portion 15 and through the ventilation hole 8 of the frame body 6 into the cavity 5 of the outer wall 3. . On the other hand, the waterproof portion 12 includes a sealing piece 19 arranged along the lower surface 3a of the outer wall 3 in front of the frame 6 from the upper end of the front rising portion 15 and the ventilation portion 11 from the front end of the sealing piece 19. The hanging piece 20 that hangs downward from the mouth 16 is integrally formed, and the hanging piece 20 covers the front of the vent hole 16 of the ventilation portion 11 to ensure the waterproofness of the vent hole 16. In the figure, 21 is a sealing material and L is a base top end.

As described above, the parting edge 10 is divided into the ventilation portion 11 and the waterproof portion 12, and the waterproof portion 12 prevents rainwater from entering the ventilation hole 16 in the ventilation portion 11, while the outside air is exposed to the outside air as shown in FIG. As indicated by an arrow A in FIG. 2, the water is introduced into the cavity 5 of the outer wall 3 from below the hanging piece 20 in the waterproof portion 12 through the ventilation hole 16 and the ventilation hole 8 of the frame body 6. By constantly drying the air, it is possible to prevent condensation and freezing and thawing in the inside of the outer wall 3 that cause warping of the outer wall 3 and generation of mold as in the past. Therefore, the parting edge 10 can have the ventilation function while having the conventional waterproof function. Even if rainwater enters through the ventilation hole 16, the rainwater may be smoothly discharged to the outside through the drain hole 18, and may enter the ventilation hole 8 located above the ventilation hole 16. Since the water is completely eliminated, the waterproof function of the parting edge 10 is sufficiently ensured.

Another embodiment of the present invention is shown in FIG. In this embodiment, the parting edge 10 'disposed between the outer wall 3 and the foundation 1 is formed in a box shape, and the upper surface of the parting edge 10' extends from the lower surface 3a of the outer wall 3 to the lower surface 6a of the frame body 6. And a vent hole 30 is provided at a position corresponding to the vent hole 8 of the frame body 6, and a vent hole 16 and a drain hole 18 are formed on the lower surface of the parting edge 10 'in front of the foundation 1. Therefore, as shown by the arrow B in FIG. 2, only the outside air is taken in from the ventilation hole 16 on the lower surface of the parting edge 10 ', and this outside air is vented from the hollow portion 17' of the parting edge 10 '. 30, the air in the cavity 5 of the outer wall 3 is always dried by being taken into the cavity 5 of the outer wall 3 through the ventilation holes 8 of the frame body 6, so that the warp of the outer wall 3 and the generation of mold can be prevented. Can be prevented. Moreover, by providing the ventilation port 16 on the lower surface of the box-shaped parting edge 10 ', it is possible to reliably prevent the entry of rainwater from the ventilation port 16, and even if it does, the drainage hole 18 can be used. As it is drained, the waterproof function can be enhanced. In addition, since the parting edge 10 'is formed in a box shape, there is an advantage that the strength of the whole parting edge 10' is increased.

【The invention's effect】

 As described above, the present invention attaches the outer wall to the wall fixing fitting fixed on the foundation, attaches the parting edge along the lower surface of the outer wall between the outer wall and the foundation, and provides the vent hole in the parting edge. By providing a ventilation hole in the frame of the outer wall with a hollow interior that communicates with the ventilation hole, the outside air is taken into the cavity of the outer wall from the ventilation hole of the cut-off edge through the ventilation hole. As a result of preventing dew condensation, it is possible to prevent the warping of the outer wall and the generation of mold by giving the cut edge a ventilation function in addition to the conventional function.
